> FELIX-737 is a framework issue but the same issue also exists in the
> standalone resolver implementation. I am opening a separate bug to
> specifically address the issue in the standalone resolver implementation.
> The felix framework resolve has a known issue with substitutable exports
> FELIX-737. The scenario is pretty complex. It involves bundles multiple
> bundles that export and import the same package X at different versions and
> an importer that imports the package with a range that requires a specific
> package. If that specific package gets substituted there are cases where the
> resolver will return wires to the substituted export.
> The ideal solution would do something smart with selection of substituted
> exports so that different combinations or selections can be made if the first
> substitution did not provide good results. This potentially will explode the
> permutations. For now we should at least change the current permutation to
> drop the substituted exports so that invalid wires do not get created. That
> could drop some good valid combinations, but that is better than the current
> state where completely invalid wires get created.
